That is false!
Hydrogen and the ( name of metal ) chloride, sulphate or nitrate. eg Hydrocloric acid and iron - hydrogen and iron cholride
Iron dissolves in acid, which is not the same thing as melting. If the acid is, for example, sulfuric acid, the iron would become the soluble salt officially known as ferric sulphate, whereas melting iron does not undergo a chemical change, just a phase change.
Most metals react with dilute acids to form metal salts and hydrogen gas. For example, metals like magnesium, zinc, and iron will react with acids such as hydrochloric acid or sulfuric acid to produce hydrogen gas.
Do you mean seperately?If yes, then:When they react with air, it is combustion: 2Ca + O2 --> 2CaOWith water, they simply come to be hydroxides: Na + H2O --> NaOH + H2When they react with acids then a salt and hydrogen gas is formed: Zn +2HCl --> ZnCl2 + H2
Magnesium produces more hydrogen gas when reacting with an acid compared to iron. This is because magnesium is higher in the reactivity series and can displace hydrogen from acids more readily than iron.
I only know 3 metals that react with acids to produce hydrogen. They are Zinc, iron and magnesium. There are 3 acids which react with them: and It will produce hydrogen gas which is the lightest known gas and is flammable :)

Magnetic properties: Iron is attracted to magnets. Density: Iron is a heavy metal with a density of about 7.87 g/cm^3. Reactivity with acids: Iron reacts with acids to produce hydrogen gas and the corresponding iron salt.

There is a fault with the question. Acids react with metal -TRUE What metals react - all will with the right acid - some need extremely strong acids -gold for example needs aqua regia
Zinc is a metallic element that readily reacts with acids to produce hydrogen gas. It is also known to form compounds with a wide variety of elements, such as oxygen, sulfur, and chlorine. Zinc is commonly used in galvanization to protect iron and steel from rusting.
Some metals such as iron react with steam to produce hydrogen gas and metal oxides. The metal oxide is formed as a result of the metal reacting with oxygen from the steam.
the metal with 'hydroxide' on the end, e.g. iron hydroxide.
Yes, hydrogen gas can be used as a reducing agent to convert iron oxide (Fe2O3) into elemental iron. This process involves heating the iron oxide with hydrogen gas, which reacts with the oxygen in the iron oxide to produce water vapor and elemental iron.
